Concept Review
The Clever Closet eliminates the daily confusion of “what should I wear
today?”. It manages the consumer’s wardrobe by integrating with the daily
clothing needs of the consumer (based on calendar, weather, etc.) and
suggesting clothes appropriate for the occasion.
Status Update
Prototype implemented!
Metrics

End-to-end latency
 The time from when the user makes a change
on the UI to when that change is reflected in
the suggestions

Scaling
 How does the size of the closet affect the
above metric
5
Latency: Measurements

Measured for three inputs:
 Change in weather
 Change in calendar entries
 Updated RFID tag information

Took 10 readings for each

Sources of Jitter: Since most of the
variable performance was associated with
communicating with the server
 Internet connection speeds
 Server response time

Scale : Measurement

Measured the end-to-end latency with
different closet sizes.
 Measured for sizes 2,4,8
 Simulated the software part for 16, 32.

Scale: Analysis

The trend line is linear - barely!

This is expected: since most of the
latency comes from communication with
the server - GET and POST requests - the
number of requests stay the same, and
the payload does not become too large.

Scale: Analysis

What to expect?

For an extremely large closet (>1000), the
time breakup would start looking different.
The server communication will not scale
as much as the interaction with the
hardware (lighting up LEDs, etc.).

Future Work

Potentially integrating the RFID scanner
with an XBee to make it mobile

Packaging the product
